buffermapping's Issues

Valid signal of line buffer when last level is not a register

When the last level of a line buffer is not a register (such as in multichannel convolution), there are multiple valid signals connected to self.valid:

Error Validating def
ERROR: Cannot connect multiple outputs to an inputs
In Module: DesignTop
  self.valid : BitIn <== ub_hw_input_stencil_update_streamlinebuffer_bank_0_1.valid
  self.valid : BitIn <== ub_hw_input_stencil_update_streamlinebuffer_bank_0_0_1.valid
  self.valid : BitIn <== ub_hw_input_stencil_update_streamlinebuffer_bank_0_1_1.valid
  self.valid : BitIn <== ub_hw_input_stencil_update_streamlinebuffer_bank_0_2_1.valid
  self.valid : BitIn <== ub_kernel_streamlinebuffer_bank_0_1.valid
  self.valid : BitIn <== ub_kernel_streamlinebuffer_bank_0_0_1.valid
  self.valid : BitIn <== ub_kernel_streamlinebuffer_bank_0_1_1.valid
  self.valid : BitIn <== ub_kernel_streamlinebuffer_bank_0_2_1.valid

Example is from 16x16x32 3x3 convolution.

New Rewrite Rules

• Storage Flatten with more complex access pattern, for example, sram in the new memtile architecture.
• Banking strategy with block, cyclic.

Update of Address Pattern

• Shall we add an invalid cycle like atherling?
• Add a state for quasi-affine access pattern if we are doing division and round.

arbitrary address mode is broken

Reading any address in the arbitrary_addr/manual_switch mode returns 1 regardless of the address passed in.

CoreIR Unified Buffer shared object File name change

Change libfuncubuf.so to libcoreir-lakelib.so

Coding Issue

• Linking C++ Functional Model with the Python Class
• Use PyBinding to link the cfunc of unified buffer with the python rewrite rule unified buffer class. Currently they are separate.
• Use PyCoreIR instead of parsing the json file.
• Reference to how aetherling did this.
